CARPENTERS TOOL.

SPECIFICATION forming part of Letters 1? Application filed May 31, 1900.

J.() 0,2] 1.0700112, it may concern:

Be it known that I, ELIHUE M. HEMBREE, a citizen of the United States,residing at B- anoke, in the county of Milton and State of Georgia, haveinvented certain new and useful Improvements in Carpenters Tools, ofwhich the following is a specification.

This invention relates to carpenters tools; and the object thereof is toprovide a cheap, durable, and efficient device adapted to be employed asa mortising-gage, thumb-gage, try-square, bevel, com passes, or rule, asoccasion may demand.

With this object in View the invention consists in certain novelcombinations of parts and peculiar details of construction, all of whichwill be fully described hereinafter, recited in the appended claims, andillustrated in the accompanying drawings, in which- Figure 1 is aunderneath perspective view of my invention, all the parts beingassembled. Fig. 2 is an obverse view in perspective Fig. 3 is a top planview of the same, the end of the rule carrying the pencil-clip being insection. Fig. etisa cross sectional view of the head-block, showing thesquare and pencil-carrying arm in elevation; and Fig. 5 is a transversesection on the line 5 5 of Fig. 3.

The head or gage block designatedby the reference-numeral 1 comprises arectangular block provided at one end with a slotted socket or recess 2,in which is slidably secured a scribe-bar 3, carrying at one end a pointor pin 4, which projects through the elongated slot 5 of the recess 2,said bar 3 being secured in any desired adjustment with relationto thegraduatedscale 6, arranged along one edge of the slot by means of asetscrew 7. The other end of the head-bar 1 is also provided with acylindrical recess 8, in which is slidably secured the cylindrical rib 9of the gage or guide bar 10, the head 11 of this bar being connected tothe rib 9 by a connecting-rib 12, which projects through the. slot 13 inthe lower face of the bar 1, and whereby the metallic-faced edge 14 ofthe gage or guide bar may be held, in proper relation to therigidly-secured scribe-point 15, connected to the head-block at a pointinteratent No. 663,168, dated December 4, 1900.

guide-bar, so that either the scribe-bar or the guide-bar may beadjusted toward and away therefrom, the purpose of which will behereinafter apparent.

Transversely through the head-block and intermediate the ends thereof isarranged a slot 16, in which is loosely secured a bearingplate1.7,having slotted right-angular end flanges 1S and 19, which areengaged by the projecting pins and 21 in each side of the head-block 1to form guides for the plate 17. and adjustable hinged bar 22 is securedin the slot 16 and held in any predetermined adjustment by a headedset-screw 23, which is adapted to bear against the under side of thebearing-plate 17 to cause the same to bind against the short arm 24 ofthe said bar. The point 25 on the head of the set-screw 23 is designedto form or constitute the pivotal point of a compass, as will bepresently apparent. As has been mentionedheretofore, the bar 22 ishinged and comprises the short arm 24:, (which is designed to be engagedby the bearing-plate 17,) and a long arm 26 is pivoted thereto at 26 andhas on one side a series of graduations to provide a scale or rule formeasuring. The projecting point 27 is to be used in conjunction-with thehead-bar 1 as a guide, making a single gage forbroad gaging. V 28designates an opening in the free end of the long arm26, in which can beheld a pencil such as the one designated by the reference-numeral 29. Inorder to securely retain the pencil in the hole or opening 28, Ipivotally secure a pencil-retaining clip 30 to the end of thearm26,which comprises astrip of spring metal curved to form a segmental bar31, on one end of which is a contact-finger 32, to impinge against theside of the pencil when in the opening 28. This finger is held incontact with the pencil 29 by forcing or springing the shoulderedextension 33 at the other end of the bar 31 into engagement with thenotch 34 in the end of the arm 26. It will also be noticed that at theend of this finger is a semicircular extension which embraces the penciltoforce the same against the side walls of the opening when the shoulderextension. 33 at the outer end of the bar 31 is held in engagement withthe notch 34:.

mediate the pin on the scribe-bar and the As soon, however, as theshoulder 33 is re- Aslidable' of the mortise having been determined, thescribe-bar 3 will be adjusted in the recess or f socket 2 to space thepoint 4 a proper distance from the point 15. bar will also be properlyadjusted with relation to the pin or point 15, and the headblock canthen be moved along the piece of stuff to scribe the proper outline forthe mor tise. In using the device as an ordinary thumb-gage theguide-bar 10 is to be adjusted so as to dispense with point by receivingsame into a vertical slot in face 14:. Leavingface 14 as the guide, thenadjust scribebar 3 to distance desired and use point 4 for scribe.Should it be found desirable to employ a try-square, the long arm 26will be hinged around on the short arm 24 until it is at right anglesthereto, and by using the longitudinal edge of the head-block as aparallel the desired result can easily be accomplished, or a bevel canbe produced by merely swinging the long arm around to the proper anglewith relation to the arm 24. Using the point 25 as the pivotandintroduci-ng thepenoil 29 in the opening 28, as has heretofore beenexplained, a compass may be provided, as will be readily seen.

It will thus be apparent to those skilled in the art to which myinvention appertains that I have provided a cheap, simple, and durabletool adapted to be used for many purposes, and while I have described indetail what to me appears to be the very best and most desirable meansof accomplishing the desirable result I would have it understood that Ido not limit myself to the exact details The gage or guide shown, butreserve the right to make suchchanges and alterations as would properlycome within the scope of my invention without departing from the spiritthereof.

I claim- 1. The combination with a block having a slotted recess orsocket ineach end, and a centrally-arranged pin projecting from saidblock, of a scribe-bar adjustably secured in one recess and carrying apoint or pin which projects through the slot, and a gage-bar in theother recess, said scribe-bar and gage-bar being adapted to be adjustedtoward and away from each other and toward and away from the central pinon the block.

2. In combination with a gage-block provided with a transverse slotextending therethrough, of a bar adjustably secured in said slot, aset-screw for retaining said bar in a predetermined adjustment, a pinprojecting from said'set-screw, and a pivoted spring-retained fingercarried by one end of said bar, and adapted to retain a pencil in anopening in the bar by frictional contact whereby the point on theset-screw and the point on the pencil will form two points of a compass.

3. The combination with a gage-block having a transverse slot extendingtherethrough, of a bearing-plate in said slot having slottedright-angular flanges, pins engaging said slotted flanges, a baradjustably secured in said slot, and adapted to be held therein bycontact with the plate, means forcing said plate tightly against the barand carrying a pivoted point or pin, and a marker carried by the saidbar.

In testimony whereof I afix my signature in presence of two witnesses.

ELII-IUE M. HEMBREE.
